Anyone else encounter event log 8528 for an exchange 2010 system mailbox. The message is he mailbox for /o=XXXX Exchange/ou=Exchange Administrative Group (FYDIBOHF23SPDLT)/cn=Recipients/cn=FederatedEmail.4c1f4d8b-8179-4148-93bf-00 has exceeded the maximum mailbox size. This mailbox cannot send or receive messages. Incoming messages to this mailbox are returned to sender. The mailbox owner should be notified about the condition of the mailbox as soon as possible.

Ok so why are quotos being applied on a system mailbox in the 1st place. If I use the getmailboxstatistics it shows me 34 items and under "storage limit status" shows mailbox disabled

I think I could use the set-mailbox comlet and set the usedatabasequotadefault $false if I add the -arbitration to the command but again why would I even need to do this in the 1st place
